OpenSearch minimum should match nto working properly

If I run this query below:

GET test/_search
{
  "size": 4,
  "query": {
    "match":{
      "court_name": 
      {
        "query": "Texas",
        "analyzer": "standard",
        "minimum_should_match": "2<10% 3<30% 4<20%"
      }
    }
  }
}

I'm able to find the document. But when I add an irrelevant word like "Texas banana" it finds no results! It should still find the document that was found earlier. What's happening?

Solution

  • the parameter minimum_should_match in the match clause define the number of words that the match query should match in your example you specify 2<10% which means if the match query contains 2 words or less it must match the two words in order to return a results if the query contains more than 2 words it should match 10% of the given words in your case if you try "Texas banana apple" instead of "Texas banana" you will match the document that you re looking for
